ABSTRACT:
An electrical flasher circuit has improved operating characteristics, in particular by providing continuous illumination for a long period of time from a fully charged solar battery. The circuit employs a solar battery recharging circuit component that achieves full charge in a short period of time. The flasher circuit may be used in roadside warning device having a sign member with a warning image. Placed around the warning image are a plurality of light emitters for providing a visual warning during evening and night hours. The light emitters are powered by a solar energy source connected to a flasher circuit including an oscillator for causing the light emitters to be energized in a particular sequence. When the device is exposed to sunlight, the battery is disconnected to avoid unnecessary draining of the battery.
